according to tf.nist.gov:
Why is UTC used as the acronym for Coordinated Universal Time instead of CUT?

      In 1970 the Coordinated Universal Time system was devised by an international advisory group of technical experts within the International Telecommunication Union (ITU). The ITU felt it was best to designate a single abbreviation for use in all languages in order to minimize confusion. Since unanimous agreement could not be achieved on using either the English word order, CUT, or the French word order, TUC, the acronym UTC was chosen as a compromise.

according to the LCD encyclopedia (lowest common denominator), i.e. WIKI says:

Coordinated Universal Time is abbreviated UTC. The International Telecommunication Union wanted Coordinated Universal Time to have a single abbreviation for all languages. English speakers and French speakers each wanted the initials of their respective language's terms to be used internationally: "CUT" for "coordinated universal time" and "TUC" for "temps universel coordonné". This resulted in the final compromise of using "UTC"

1. connect to http://docs.fedoraproject.org/install-guide/f10/en_US/sn-utc.html

Actual Results:  
10.2. Universal Co-ordinated Time (UTC)

For purposes of addressing time zones, Universal Co-ordinated Time is also known as Greenwich Mean Time (GMT).

If Fedora is the only operating system on your computer, select System clock uses UTC. The system clock is a piece of hardware on your computer system. Fedora uses the timezone setting to determine the offset between the local time and UTC on the system clock. This behavior is standard for UNIX-like operating systems.
